If a 30mm isn't an option, the Leupold 1.5-5x is probably your best bet. I have a handful of the Nikon African 1-4x on Ruger No. 1's and like it for that application. I also have a Leupold 1.5-5x and feel it has better glass than the Nikon. I'm not aware of other currently available LPV's with 1" tubes other than Leupold.
